T on whom it may concern:

Be it known that 1, JOHN J. QUAcKENBUsn, a citizen of the United-States,residing in Lakeview, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in'Blind-Fasteners andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled. in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

My invention relates to attachments for blinds or shutters havingpivoted slats, and it has for its object to provide a device of thegeneral nature above indicated designed especially for securing theslats of the blind or shutter either open or closed, and, as a furtherobject, to provide a mechanism which shall comprise in a singleorganization means for both securing the slats of the blind or shutterand for securing closed the blind or shutter itself.

My invention will be found fully illustrated in the accompanyingdrawings, wherein- Figure 1 is an inside view of blinds or shuttersprovided with my attachment. Fig. 2 is a horizontal sectional view ofthe blinds, taken just above the attachment constituting my inventionand showing the slats held closed. Fig. 3 is a view similar to Fig. 2,but'showing the slats held open; and Fig. 4 is a vertical sectional viewtaken just to the right of the attachment, as seen in Fig. 1.

On the meeting rail of each blind or shutter a, hinged in the easement bin the usual manner, is secured an elongated plate 0, 6X". tendingvertically. At the outer edges of these plates are arranged leaves d,which are pivotally attached to the plates by means of hinges 8, whosepivots stand out from the plane of the plates in such manner that whenthe leaves are swung around on the hingesinto the position shown in Fig.3 there is clearance between the adjacent edges of each plate and theleaf. The object of this will be explained later. Each leaf is bentlongitudinally at right angles, so that when the leaf lies against theface of the meeting rail of the blind the bent-off portion f extendsaround the edge of the meeting rail and takes against several of theslats of the blind, it being understood that saidslats are at this timein their closed position. In order to lock theleaves in theposition justdescribed as that where they hold the slats closed, I provide a latch orbar g, having its pivot on a stud h, which may project from one of theplates 0. The blinds being closed, this latch is held in the horizontalor securing position by means of a keeper 1', which may be convenientlyattached to the other plate 0. I11 order to prevent the latch beingmanipulated from the outside of the blind, a guard j is pivoted on oneof the plates 0 in such manner that when suspended vertically from itspivot 7.: it takes against the top of the latch to hold the same down inthe keeper. Latch g is also adaptedto secure the slats in their openposition. To this end, and as bestseen in Fig. 3 and alsoin dottedoutlines in Fig. 4, latch g is made long enough so that it extends, whenin the horizontal position, in the path of movement of two of thepivoted slats in each blind.

It is, furthermore, preferably made of such width as to just fill thespace between two adj acent slats in each blind when the same are intheir open position. (See Fig. 4:.) In order that the slats may assumethe open position and yet be engaged by the latch, leaves dare swungback into the'position shown in Fig. 3, so that the clearance abovereferred to as then existing between the hinging edges of the leaves andthe plates 0 will permit the latch to be turned into engagement with theslats, as best seen in Fig. 3. It will be understood that in looking theslats open, since the moving of the latch on its pivot to the horizontalposition means that one end thereof must be depressed while the other iselevated, of course the two series of slats must be first arranged inrelatively reverse positions, so that when or slotted member a receivesa turn-button 0,

whose shank-p is threaded and screwed into a plate q, secured to thecasement-sill a. By

adapted to engage said series of slats to maintain them closed, saidmember being pivoted on the blind and having its pivotal axis extendingtransversely of the slats, and means for locking said member in thesecuring position, substantially as described.

2. The combination of the blinds each havin g pivoted slats, of securingmembers adapted to engage said slats to maintain themclosed, each ofsaid members being pivoted on a blind and having its pivotal axisextending transversely of the slats, and a common means for securingsaid members in the securing positions, substantially as described.

3. The combination of the blinds each having pivoted slats, of securingmembers adapted to engage said slats to maintain them closed, each ofsaid members being pivoted on a blind and having its pivotal axisextending transversely of the slats, and a pivoted latch adapted toengage in common both of said members to lock the same in the securingpositions, substantially as described.

4. The combination, with the blinds each having a series of pivotedslats, of a pivoted securing member adapted to engage each series ofslats between two of the same to maintain said slats in the openposition, substantially as described.

5. The combination of a casement, a blind arranged in said casement andhaving pivoted slats, and means for securing the slats in fixed relationto the blind and the blind in fixed relation to the easement, said meansconsisting of a relatively stationary member fixed to the blind, hingedmembers carried by said fixed member and one of Which is adapted toengage the slats, and means for interlocking the other hinged memberwith the easement, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this20th day of February, 1903.
